"This series is born nested by the spirit of making readers aware of the scaffolding, almost always invisible, inaccessible, that supports the work of some creators. We refer to the notes or sketches housed in notebooks, notebooks, folders, loose sheets, in different formats and qualities: the traces of the process to reach the final work of plastic artists, writers, architects, composers, choreographers. Photographers, poets, mathematicians, designers, filmmakers, playwrights, who resort to these instruments informally, playfully, systematically or not. "Cuadernos de autor" (Author's notebooks) is a window to those creative exercises; an element that enriches, through the reproduction not only of the content, but also of the support chosen in each particular case, the perception of the work by the viewer.
